Abstract

825,177. Automatic exchange switches. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Feb. 21, 1958 [April 23, 1957], No. 12852/57. Class 40 (4). In moving from one bank contact to the next, a wiper is deflected out of engagement with the first contact and later restored to its normal path to engage the next contact. This has the object of reducing contact wear and allowing the use of precious metals for the contacting surfaces. As shown, a pair of wipers 17, 18 engage pairs of contacts 15, 16 mounted on opposite surfaces of an insulating separator 10 having raised ribs 13 between successive pairs of contacts. The ribs 13 end in protuberances 14 which engage non-contactmaking portions of the wiper tips to bring about the above-mentioned deflection.
